Aluminum plating film base material: with its low cost, the aluminium products with excellent shading sex, decorative, barrier property and other unique properties, and the processing after printing, composite, etc with good adaptability, can satisfy the heat resistance, chemical resistance, abrasion resistance, resistance to oxygen, high barrier, such as use requirement, widely used in food packaging and other decoration field.
Aluminum plating film bag
Its development direction is:
1) improve in order to improve the stiffness of the aluminum plating quality;
2) improve plating aluminum layer adhesion after more than 2 n / 15 mm, meet the needs of the large packaging;
3) improve after plating aluminum layer heat resistance performance, meet the needs of the 300 ℃ extrusion compound, at present only reached about 240 ℃, improve the peel strength of lN/more than 15 mm;
4) to reduce the heat sealing temperature, under the condition of less than 110 ℃ heat sealing strength 5 n / 15 mm or more, to adapt the demand of high speed automatic packaging;
5) improve the opening and smooth to meet the requirements of high speed bag making and packaging, unable to add slip agent, such as the common product of COF package is about 0.75;
6) how to keep the aluminum surface wetting tension over 6 months up to 38 dyne, to extend the shelf life of the product is a problem;
7) with large aluminum plating machine, super-long extra-wide aluminum plating substrate become the inevitable development direction, such as 2500 mm wide, 24000 m long product part of the enterprise has the normalization of the production.
